基本上我正在尝试使用CSS来尝试创建一个聊天框，当我float:right聊天消息从聊天框中消失时，但是当我float:left它工作正常时在这里是JS Fiddle，它显示了这个问题！

.msg {
    word-break: break-all;
}

似乎是要走的路。 MDN

PS。事实证明break-word是word-break属性的非官方值，它应该是break-all。来自caniuse：

  

部分支持（CSS3 word-break属性）是指支持break-all值，但不支持keep-all值。 Chrome，Safari和其他WebKit / Blink 浏览器也支持非官方破解词值，该值被视为自动换行：break-word。

因此，您最好使用word-break: break-all;

请参阅下面的代码。我添加了word-break: break-word; 它工作正常。

a {
  text-decoration: none;

fieldset {
  border: 0;
  margin: 0;
  padding: 0;
}

h4,
h5 {
  line-height: 3.0em;
  margin: 0;

你必须使用

 .msg {

    width:256px; // add this 
    word-wrap:break-word;// add this
    ...//your code
}

Demo in jsfiddle

答案 3 :(得分：0)

问题在于，在现实生活中，没有具有这种大小字符的单词

试试这个：

width: 100%;
text-overflow: ellipsis;
